In this review, we aim to introduce the reader to the technique of electrical impedance
spectroscopy (EIS) with a focus on its biological, biomaterials, and medical applications. We …

Summary Formamidinium-cesium (FA-Cs) lead halide has attracted wide interest for
enhancing the stability of perovskite solar cells; however, the crystallization of FA-Cs …

The increase in the performance of organic solar cells observed over the past few years has
reinvigorated the search for a deeper understanding of the loss and extraction processes in …

An organic bulk heterojunction based on a blend of a conjugated polymer PBDB‐T‐2F
(PM6) and a non‐fullerene acceptor BTP‐4F (Y6) has come forward in recent years as an …

The mixed halide perovskites have become famous for their outstanding photoelectric
conversion efficiency among new‐generation solar cells. Unfortunately, for perovskites, little …

The photovoltaic and electrical properties of organic semiconductors are characterized by
their low dielectric constant, which leads to the formation of polarons and Frenkel excitons …

The stability issue that is obstructing commercialization of the perovskite solar cell is widely
recognized, and tremendous effort has been dedicated to solving this issue. However …
